Duduzane gives force to 'Zupta' perception

President Jacob Zuma's son, Duduzane, has a stake in the company that, with the Gupta family, is buying Glencore's Optimum Coal mine, says the competition regulator.Before Duduzane's involvement was disclosed, the transaction attracted criticism from opposition parties and unions because Mineral Resources Minister Mosebenzi Zwane said he had travelled to Switzerland to meet Glencore officials to help advance the deal in what he said was an attempt to save jobs.
